Abstract Hyperbranched polyethyleneimine (PEI) and citric acid (CA) were used to prepare fluorescent carbon dots by a hydrothermal synthesis method. It was experimentally demonstrated that the fluorescent intensity of carbon dots was greatly improved by PEI surface modification. The effects of dosage, temperature and reaction time on the fluorescence of carbon dots were investigated. Under the optimal experimental conditions, the fluorescent quantum yield of 43% was achieved. In addition, the fluorescent carbon dots were characterized by UV-vis spectroscopy, fluorescent spectroscopy and transmission electron microscopy.
